- Cuprian Dolomite cast after Calcite
- Small Cabinet, 6.8 x 5.1 x 3.3 cm
- Tsumeb Mine, Tsumeb, Oshikoto Region, Namibia
- Ex. Shields and Frances Flynn
This striking and sculptural crust from Tsumeb is composed of Cuprian Dolomite that has epimorphed over what were once sharp scalenohedrons of Calcite. The light, mint-green color is uniform and attractive, and the specimen is extremely light weight for its size, like balsa wood. The few broken tips on the epimorphs provide an interesting view into the structure and reveal that they are hollow. Hence, the pseudos are casts after the Calcite crystals. A rare, excellent, and very showy pseudomorph from Tsumeb that is even better in person.
